i havent heard of any really good games to be released for ps2 but that being said i am 100 percent sure from various game news outlets and a few
friends i know in the industry that the ps2 is a "dead" system yet so all likley hood there should be a few more good ones before it goes the way of
x-box...wich is def a dead system.
There is a link to all the upcoming releases for PS2.
As for good games I can suggest:
Amplitude
Killer 7(Weird weird weird game...can be bought for $5)
Silent Hill Series
.Hack series
Guitar Hero 1 & 2
Final Fantasy 10 and 12 (11 is an online game)
Dragon Quest 8
Tony Hawk games
WWE Wrestling Games if you play a lot of multiplayer
Devil May Cry 3 (Awesome!!!)
